Drove my daughter's car today and found the air cond not working. Looked under the bonnet and the compressor clutch wasn't engaging. Swapped some fuses and relays and its clutch energised. Swapped the parts to the original places and it is still working - however, the air is not getting chilled and I hear sloshing noises in the glove box area so I am suspecting it needs re-gassing.
Could some sort of sensor have tripped the electrics to give the original fault?
Would running it with low gas cause a problem - should I remove the fuse to stop anyone trying to use it? (It is booked in for a service in about 4 week so I will get it fixed properly then)
